UI Panel, Button with Vuforia Image Targeting

I am sorry BEGINNER HERE!
I do have Multiple Targets on my hierarchy
I wanted to give INFO to my First Image Target

Brief Explanation:

1. Scanning the Image Target then shows 3dObject or Video
2. A Button appears when 3Dobject or Video is showed
3. The Button is called INFO ( using a PANEL to show the information of the First Target )
when button is tapped it will show the PANEL of INFO

QUESTION: How can i show the specific Panel of INFO from a specific Image Target by the camera ("THE INFO is TOGGLED in a button) and NOTE: I have multiple targets



Hope someone can help!
